12.4.1. Formulas / Calculations
12.4.2. Annex – formula heating index
The heating index (hi) is calculated according to the following formula:
hi = c1 + c2·T + c3 · p + c4·T · p + c5·T^2 + c6·p^2 +c7·p·T^2 + c8·T·p^2 + c9·T^2·p^2
with
T=Temperature in °C
p=rel. humidity in %rH
c1 = -8.784695,
c2 = 1.61139411,
c3 = 2.338549,
c4 = -0.14611605,
c5 = -1.2308094e-2,
c6 = -1.6424828e-2,
c7 = 2.211732e-3,
c8 = 7.2546e-4,
c9 = -3.582e-6
12.4.3. Annex – additional information regarding the heating index
Remark:
At increased temperatures, keep away from the heat!!
Ozone levels can be elevated in this case!
Index: 27-32
States of exhaustion are possible at longer duration and/or physical activities
- avoid midday heat -
Index: 32-41
Sunstrokes, muscle cramps, heat exhaustion are possible at longer duration and/or physical activities
-avoid midday heat -
Index: 41-54
Sunstrokes, muscle cramps, heat exhaustion probable, heat-stroke possible at longer duration and/or
physical activities
-avoid heat in general/attention-
Index: 54 and higher
Sunstroke or heat-stroke probable
12.4.4. Annex – formula Humidex
The Humidex (hx) is calculated as follows:
hx = T + (3.39556) · e^[19.8336 - 5417.75/(D+273.15)] - 5.5556
with
T = Temperature in °C
D = Dew point in °C
